Abstract:
The objective of this paper is twofold; First, it develops an excel program referring to the governing values of Geometric design manual of Ethiopia in order to identify and quantify inconsistent geometric design on Mettu-Gore road. In order to achieve the first fold of the study, the final As-built geometric design on Mettu-Gore road and the geometric design policy of Ethiopia have been used. Second, it assesses the geometric characteristics of police-reported hotspot zones of the road. The result was confirmed that road geometric parameters such as; Radius of a curve, Superelevation, Gradient, and Sight distance are the most significant factors affecting road safety on Mettu-Gore road.
